BRICK OR TILE DIE.

SPECIFICATION forming part of Letters Patent No. 331,391, dated December1, 1885.

Application filed June 30, 1885. Serial No. 170,287. (No model.)

To all whom it may concern:

Be it known that I, JEssE L. FRIEND, acitizen of the United States,residing at Perrysburg, in the county of Miami and State of Indiana,have invented certain new and useful Improvements in Brick and TileDies; and I do hereby declare that the following is alfull, clear, andexact description of the same, reference being had to the annexeddrawings, making a part of this specification, and to the letters andfigures of reference marked thereon.

Figure 1 of the drawings is a perspective View of my improved die; Fig.2, a transverse section thereof, and Fig. 3 a detail plan view of one ofthe die-sections with the packing partly broken away.

The present invention has relation to certain new and usefulimprovements in brickdies for attachment to a tile-mill, or any machinethat forces tempered clay into a mold or through the same, the claybeing forced through upon a platform or belt movable as the deposit ismade by passing through the die and afterward cut into brick or tilelengths by a wire or other device usually employed.

The invention consists in the details of con struction, substantially asshown in the drawings, and hereinafter described and claimed.

In the accompanying drawings Ihave shown the die as constructed of threeindependent sections, A B 0, although a greater or less number may beused, as found desirable. Each section is divided into any preferablenumber of openings by transverse partitions a, and the sections areformed with perforated lugs 5, through which pass headed screw-bolts c,the screw-threaded ends thereof receiving the nuts d. This is one ofmany means that may be employed to securely fasten the severaldiesections together, and therefore I lay no claim to any special means.The die-section A is provided with a plate, D, for convenience inattaching the die to the machine by bolts, clamps, or other suitablemeans. Each section of the die upon its contacting face is formed with agroove, 6, extending around it for the passage of thelubricating-liquid,which is introduced through the pipes f, the same communicating with thegrooves in any convenient manner. Communicating with the groove 6 aresmall grooves or channels 9, extending out through the inner Walls oftheopenings E, and between each section is placed a packing of felt orother suitable material, as shown at F. The water is introduced throughthe pipesf, and fed to the die from a reservoir, and as it passesthrough the pipes it escapes through the felt packing F, between thesections, and also at the corners and sides through the channels 9. Bythis means water is furnished all around the die as a lubricant to theclay passing through, and by the channels g at the corners of thedie-sections a perfect angle or corner is made to the brick.

The felt packing F, which is interposed between the die-sections, may beremoved and replaced by new packing when two much worn, or so stopped upor puddled as to prevent the proper amount of water filtering through.

The side walls of the openings E in each diesection are flaring, asshown more clearly in Fig. 2, .forming a decrease in the size of theopenings, which is continuous from one section to the other, thuseffecting a gradual compression of the clay in passing through the diefrom section A to section 0 without any repeated motion, but by acontinuous pressure, which acts uniformly. The flaring walls of theopenings E present an offset or shoulder, h, upon which rests the inneredge of the packing F. These offsets or shoulders it serve the furtherpurpose of p reventing friction throughout, as in passing from section AtoBthe compressed clay does not touch the section B until it is near themiddle, from which point it is further compressed until it passesthrough the section, when the clay passes in like manner to thedie-section 0, receiving final shape and finish.

The felt packing F, being interposed between the die-sections andconnecting with the grooves e and chambers more efiectually andthoroughly lubricates the die throughout, and especially in the center.

The offsets or shoulders h protect the felt packing from wearing, as itforms no part of the sliding surface with which ithe clay comes incontact.

The method of lubrication, also the progressive condensation of theclay, is as equally applicable to tile dies or machines 5 and Itherefore do not desire to limit my invention to a brick-die.

The offsets or shoulders and the tapering openings through the die whichrelieve the pressure on the clay as it passes from one of thedie-sections to the other leave space by which the lubricant is freelydistributed on the face of the die. 7

Any packing of cloth or felt that is sub- 10 jected either to a director sliding pressure quickly becomes worn, and requires frequent renewal,and especially when sliding on such surface it has a tendency to puddlethe same, thus rendering it more difficult for the water to percolatethrough, which objections are entirely removed by the offsets orshoulders and tapering form of the openings in the die.

what I claim as new, and desire .to secure by Letters Patent, is-

1. A die for brick, tile, or other clay-worko ing machines, formed insections detachably connected together, each section having a groove forthe lubricant, a packing interposed between them, and an offset orshoulder formed by the increased width of one of the 35 contacting facesof the die-sections, substantially as and for the purpose specified.

2. A die for brick, tile, or other clay-working machines, consisting oftwoor more detachable sections, each having a central groove 0 and aseries of transverse channels communicating therewith, packinginterposed between the sections, and offsets or shoulders formed by theincreased width of one of the contacting faces of the sections,substantially as and 5 for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

JESSE L. FRIEND.
